Patented Juncal?, 1913,

To all whom it may. concern Be it vknown that l, lViLi-rnmr Bannon), a subject ofthe German Emperor, and resident `of Charlottenburg, Germany, have invented certain new and useful Improvements in Apparatus for Quenching Coke, of which the following is a specification.

`My invention relates to a device for quenching-coke, particularly in cases where large masses of incandescent coke are to be quenched, asin the operation of coke ovens, chamber' ovens for the production or Villuminating gassin.

The object of my invention is to provide a colrequenching apparatus which will be of lvery simple construction and greatl reliability in operation, enablino the 'incandescent coke .to be quenched thoroughly with the use olie minimum quantity of quenching liquid, for instance water, that, is to say, without drenching the Vcoke with too great a quantity of quenching` duid.

Another'objectfozny invention is to sub- '.ject the trough receiving the incandescent coke,` to an eflicient cooling action 'durin the entiretime vthatlthe coke is discharge into said trough, so as to protect the trough against Aexcessive wear and premature destruction.' 7 A In the .accompanying drawings li have shown as an example, one form of quench- "ing apparatus embodying 'my invent-ion, Figurerl beings, vertical section on the line tf-Boi, Fig. 2, and Fig. 2`being a vertical section on the line C-D of Fig. 1. TheI :coke-quenching apparatus shown comprises aframe ,1, preferably 'mounted to travel, as on tracks 19, sol that the apparatus maybe broughtinto operative relation to 40 -any c'oking chamber of a group or bench, one such chamber being indicated at 23 in Fig. 1. On the frame 1 is iirmly secured ithe`receptaele-or tank 2 adapted to contain `the quenching liquid (say, water) supplied from :a stora'e tank 5 (likewise carried by said frame) t rough .a pipe i provided with a valve 3. The tank or trough 6 adapted to receive the incandescent coke from the oven @chamber 23 (say with the aidofa statmnary` per portions of the guides arc on the side walls or' a box or casing 19 forming in part au upward continuation of the said receptacle. A winch orvdrum 9, connected with a wire, chain or cable 10 attached to the axles of `the rollers Y, serves to draw up the coke trough 6 or to let it down. The

drum 9 is actuated by a suitable motor 25, v

16 adaptedito be closediby a slide 17 or other suitable device. At the lower Kport-ion of the tank 2 stops 18 are provided in the path of the slides 17. Thebox or casing 19 has at the vtop ia chimney -or outlet pipe 2O for the 'escape of the -steam'evotved duringthel quenching of the coke. Onthat side of the apparatus where the quenched coke is vto be discharged, a funnel or hopper 21 is arranged, at a proper height to .deliver .the coke, say to a car 26. Onthat si'de of the tanlr 2 which. is near the hopper 2G, l pro vide a ,guide 22 .adapted to engagea projection 6a on the trough 6 and to governthe vertical movement ,and tilting of said trough, the guides 8 and 22 coperating to produce the desired motion of the trough as it is raised or lowered by the cable or chain 10.

According to my invention 'the weight ,and the dimensions of the coke trough 6 are so selected that'before receiving' its charge of coke,'the` trough will lioat in the quenching liquid contained in the tankl 2, as indicated 1n the drawings by solid'lines.y In this position, the cheeks 13 connected with the bottomll will project partly above the level of the liquid, and since the slides '17 are in the closed position, the quenching liquid will be in contact only with the outer 4surface of the tank, at its lower portion, but

will have no access 'to the interior of the A tank. .The only eect ofthe liquid .at this time will be to cool the lower part of the tank 2 externally.

As soon as the trough 6 is Weighted lby incandescent coke delivered thereto A(say from the chamber 23), the trough will sink more and more in the quenching liquid, until the'upper edges ot the cheeks 13 are below the surface so that the liquid lmay l'ow into the pockets lll through the inlets formed by their open upper ends and thus reach the, compartment l5 from which it passes through the perforated false bottoni 12 into the body ot' the trough G, that is to say, yinto the chamber containing the incandescent coke. Finally, `when the trough has, received its full charge, it takes thel lower position indicated in Fig. 2-by dotted lines, the slides 1T being arrested by engaging the stops 1S, while the trough continues to move downward for a short distance, thus uncovering the openingsl. It will be understood that the water or other liquid rising through the perforated false bottoni 12 will quench the. incandescent coke contained in the trough 6. i Thefcokc having been quenched, the wind-` ing drum 9 is actuated to pull the trough ti up from the quenching liquid, the dripv 'pings' and the excess of liquid escaping.

through the openings 16 which are still uncovered. VThe guides" S, 22 cause the trough `6to be .tilted as it is raised, bringing it'into the dumping position illustrated by dotted lines in` Fig. l. rl`his Vcauses the quenched coke to be discharged through the hopper 2l, say into a ear 2G.

Betere the trough 6 is again lowered into the liquid, to receive a new charge of in-` candescent coke, the slides 17 are closed by the attendant or in anyvother suitable manner.

quenching operation is practically limited to that converted into steam and escaping.
